JDAM

Definition
JDAM (Joint Direct Attack Munition) is a low-cost guidance kit developed for the U.S. Air Force and U.S. Navy that converts existing unguided, free-fall bombs into all-weather precision-guided munitions. By replacing the bomb’s tail section with a guidance and control module that combines GPS-aided inertial navigation (INS/GPS) and movable tail fins, JDAM enables aircraft to strike fixed or relocatable targets by steering the weapon to preplanned or in-flight updated coordinates. JDAM kits are used with common bomb bodies (for example, Mk 80-series and BLU warheads), turning standard inventories into accurate “smart” weapons without requiring laser designation.
